I saw that my answer to this question:
I did check the FAQ to see if I could figure out why, but I sincerely don't get it. It's an old answer that's been there for a couple of years now. My answer was the only one that addressed the actual bug in the question's code, short and to the point, without any link and answers precisely what's wrong with the code.
Is this the correct venue to ask for a clarification? It'd be nice to get a comment when something is deleted, so that you don't go wondering what you did wrong.
